Sorry but I am not going to debug any emulation problem that is not simple "not working at all/crashes" when OS is "alien". Too much work x 100. (Unless OpenBSD sources reveal the problem easily)

It all works (TM) so I'm not complaining. Not a dev so pinpointing that stuff is way beyond my skill set. It hasn't been supported since 2003 anyway.. The hanging in 3.0 is moot, although I'm surprised it's a 68040 issue, not an i/o driver issue.
